Sóller is a town and municipality near the north west coast of Mallorca, in the Balearic Islands of Spain. The town is some 3km inland, from the Port de Sóller, in a large, bowl-shaped valley that also includes the village of Fornalutx and the hamlets of Biniaraix and Binibassi. The combined population is around 13,000. A famous tramway, the Orange Express links Sóller to Port de Sóller.

Sóller is linked by the historic railway, the Ferrocarril de Sóller, and by a highway with a toll tunnel, to the Majorcan capital of Palma. The Andratx-Pollença highway also runs through the valley. The Ferrocaril was completed in 1911 after work began on the profits of the orange and lemon trade.
